I think it only applies if your specifically targeting off duty police. We've had a steep raise of cops being targeted off work in the last couple years.
Not trolling but rather quite serious - please define, or link to something that explains, "steep rise" in absolute and percentage terms. I mean going from 2 to 3 is a 50% rise and sounds dramatic but may in fact be a fairly limited problem. I just don't know the scale of what you are discussing.
